Electric Weight: with or without batteries at US Nationals

[Adam Glatt]

Jim, the Thunder Power 5s4p 5300 pack is in stock with free courier 
shipping at parts.rctoys.com .

I'm using a 6.0v regulator (JR servos) with my 2s lipo receiver pack, 
and used a mere 290mAh in 51 minutes of flight yesterday.  My fellow 
team members are using Futaba servos with a 5.6v regulator, and seeing 
50-60mAh per a 10 minute flight.  You can definitely cut receiver 
battery weight.  My TP 2s730 weighs 31g.

BTW, in Canada we changed our rules this year such that electric pattern 
planes are weighed without the battery that powers the motor.

If you want a killer deal on the 2s730 with a 5300 order, ask for me ;>
